Hi,
DI job to import the excel sheets is simple if you are using a basic proc import code in User Written code transformation.
But this can lead to some issues while importing data. Normally, If I am not wrong these excel sheets are used by employees who would not think of formats for a column while writing a data into it. You can even receive a column with Zero (0) entered in it for all its rows in one month and character data next month, even if its understandable from the column name that it should be a character.
Now the problem you will face is that when you are importing the sheet with character column having Zero in it then proc import will by default assign the data type for that column as NUMERIC, and when the next month data comes where it is a character as it should be defined for the same table, It will throw an error since while creating the table it was numeric, and now inserting character data in it.
So you need to figure out a proper format for all the columns and transform those columns in that format as required.
Then you can insert the data monthly.
Believe me it could take a while initially for the problem to be solved, but when you complete it then it becomes quite easy to use the code for many other purposes.
Do reply to it if you need any help. I have the code for such an import done already.
Thanks & Regards,
Saurabh
